Consequences of the mode of writing

The text must be produced as a coherent whole and not in a continuing dialogue,

it is not possible to point to the context with the body, so pointing to the context must be done by textual cues (deixis) and explanations,

the producer is likely not to know the exact knowledge and background of the consumers, so he must set out more explicitly what he intends to express,

the producer only has a limited knowledge of what the consumer think of what the producer utter, and therefore does not know precisely what the consumer concieve of the utterance (get insulted, sorry about, tired of etc.).
